GYM9 DC-6KA 1P MCB For PV

GYM9-63DC circuit breaker is used for DC rated voltage to 1000V, rated current to 63A line, for overload and short circuit protection, and can also be used as an infrequent operation of the line. Circuit breakers are used in DC applications such as communications and photovoltaic system.

 

Description

What is The Circuit Breaker?

The circuit breaker is a popular design pattern used to limit cascading failures in distributed systems. It operates automatically without the need for an external power supply, unlike a fuse. It was developed to protect electrical circuits from being overloaded. One of the main benefits of this protection system of the circuit breakers is that it prevents damage that could happen due to short circuits and power surges. The damage could be happened due to short circuits, overloads, fault current, direct current, high voltage, and high pressure of electricity, electrical shock or huge current interruption. This is a very efficient method of protection and can be found in almost all industries. Technologies used in circuit breakers include removable fuses, plug fuses and fuse wire, miniature circuit breaker, micro miniature circuit breakers, circuit breaker panel and a variety of other methods which serve to protect electrical devices from any excessive heat and load.

The circuit breakers also function as devices that prevent electrical fires by turning off the flow of the electricity to a circuit or device which is faulty. In the electrical systems found in modern buildings, an overcurrent protection device is also known as a fuse or circuit breaker. Circuit breakers are a type of fuse which protect electrical equipment and devices from overheating by opening the circuit when it detects too much current flow.

Types of Circuit Breakers

There are many circuit breaker types and a wide range of styles and shapes as well as some certain types for particular applications. In general there are circuit breakers such as thermal safety, magnetic safety and pressure safety or other generic types like standard circuit breakers, ground fault circuit interrupters (GFCI Circuit Breakers), and arc fault circuit interrupters (AFCI Circuit Breakers). Other circuit breakers types are like:-

  • High voltage circuit breakers.
  • Low voltage circuit breakers.
  • Oil circuit breakers.
  • Vacuum circuit breakers.
  • Double pole circuit breakers or double pole breakers.
  • Single pole circuit breakers.
  • Air circuit breakers.
  • Ground fault circuit interrupters (GFCI breakers).
  • Air magnetic circuit breakers.
  • Medium voltage circuit breakers.
  • Air blast circuit breakers.
  • Dead tank circuit breakers.
  • Indoor circuit breakers.
  • Outdoor circuit breakers.
